I bought some infant PFs basically as soon as I found out and went to the OB to comfirm. But everything else I waited until after we found out the sex - most things i bought in the last 1-2 months (I am 29 weeks right now).

LOL I started buying nb stuff before I was even pg Mostly gn stuff or things that were a really good deal.
Then I waited to find out the sex before I really started buying and getting custom stuff, so now I have the ultra girly stash with hardly a boyish dipe in sight!

We are going to start to TTC closer to the end of this year and I just bought some infant prefolds. Next I will buy preemies and then covers in XS and S. I am a compulsive planner and feel that DH will feel more ready to TTC if I show him that we have nothing to worry about except the doc bills!
At least I'm not the only one already buying for a baby I've only dreamed about.

I TOTALLY could have written this!!! I too love planning as many details as I can. We'd like to start TTC at the end of Summer/beginning of Fall and it's so difficult to not buy anything. For now, I'm only adding free things to the baby pile (Freecycle, hand-me-downs, etc), but once I find out I'm pregnant, watch out!

Not until I was put on bedrest at 32 weeks. Until then, I hadn't had time to research, shop, etc for what I wanted. Now I have all the time in the world...which is bad, since I've been spending WAY too much money. But, it's fun.

The hard part is not knowing boy/girl, but I've been able to find some cute gn stuff out there.

I'm 18 weeks & I've only bought 1 diaper (BG egyptian cotton fitted) & 2 covers (Dappi pants & a prorap). I'm planning on sewing most of my stash, so I've been holding out for the big u/s, which is in just 2 weeks. Then I'm going to be very busy.
